Wireless Screen Mirroring with OSD Transmission for Touch Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current screen mirroring technologies in wireless devices do not adequately allow users to conveniently control a source device while viewing its image, particularly in environments like living rooms where TV operation through remote controls is cumbersome and UI complexity is high.
Innovation Solution
A wireless device that receives a screen mirroring request, determines transmission conditions, and transmits content and OSD image data via a wireless interface, enabling users to control the source device through a sink device with simple touch inputs, enhancing user convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If screen mirroring is implemented using traditional remote control methods, then the TV can be controlled from a distance, but the operation becomes cumbersome and UI complexity increases
Solution Approach 1:
The patent applies the copying principle by transmitting and displaying the source device's screen interface on the sink device. This allows users to interact with the TV system through the sink device's simpler interface (such as a smartphone or tablet) while the actual control operations are executed on the source device. The visual feedback loop is established by mirroring the source device display to the sink device, enabling users to see the result of their touch inputs in real-time without navigating complex TV remote controls.
2Ease of operation
If remote control operations are used for TV control, then operation can be performed from a distance, but input convenience is reduced
Solution Approach 1:
The patent introduces the sink device as an intermediary between the user and the source device control system. The sink device receives user inputs through its intuitive interface, transmits these inputs to the source device, and displays the resulting screen feedback. This intermediary approach allows users to leverage the sink device's familiar and convenient input methods (touchscreen, keyboard, etc.) while still achieving control over the source device, thereby improving input convenience and reducing the time required for control operations.
3Adaptability or versatility
If traditional remote control is used, then basic TV functions can be controlled, but fine-grained control operations become difficult
Solution Approach 1:
The patent adds a new dimension to the control system by introducing a second display device (the sink device) that mirrors the source device's interface. This creates a dual-display control environment where users can interact with the system through the sink device's interface while receiving visual feedback from both devices. This dimensional addition enables fine-grained control operations through the sink device's precise input mechanisms while maintaining the source device's full functionality, thereby improving control precision without sacrificing versatility.
